Gregg Allman, who died at his home in Georgia Saturday, was a crucial figure in the birth of what’s known as “Southern Rock,” a genre that includes such bands as Lynyrd Skynyrd, The Marshall Tucker Band, and Alabama.

With The Allman Brothers Band, the singer, guitarist, and organist left behind many songs that are classics: “Ramblin’ Man,” “Midnight Rider,” “Whipping Post.” You probably know more of their songs than you think you do.
